Disable screensaver and screen blanking Raspberry Pi 3

If you want to use your Raspberry Pi 3 for monitoring purposes like I do, you probably want to disable screensaver and screen blanking on your Raspberry Pi 3.

I just bought my first Raspberry a few days ago and want to dive into it and see what it’s capable of. I want to utilize this one mostly for monitoring, to attach it to a screen and run a couple of dashboards that oversee my network.

I use Raspbian as the operating system but the steps should be the same in other OS versions.

First, open a terminal window then enter:

1. sudo nano ~/.config/lxsession/LXDE-pi/autostart

You will end up in your autostart script, now we need to edit a line and add 4 new ones. Your initial autostart config should look something like this:

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash

Now we want to modify it to look like this:

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
#@xscreensaver -no-splash

@xset s off
@xset -dpms
@xset s noblank
@unclutter

Please note that we uncomment @xscreensaver -no-splash with a # in front of it!

2. Save the file by pressing CTRL+X and hit Y to confirm saving.

 

3. Reboot your Raspberry Pi 3 to load the autostart config

 

And that’s really it! Now your screen shouldn’t go blank anymore.
